In the 3-minute video below we see 100 people, filmed by Jeroen Wolf, from ages one to one hundred. The one-year-old mostly just stares, the remainder look into the camera and state their age.

What I find interesting is the uneven way that people age. As you watch the clip, people’s ages become increasingly difficult to pin down. You know that each person is about one year older than the last, but their appearance betrays this knowledge. One might look significantly older than the one before, or quite a bit younger. How old we look doesn’t ascend nicely in a linear fashion, but varies tremendously. No doubt this is based, in part, on genetics and life choices, but it is also dependent on opportunities and expectations related to ascribed identities and social structures.
